Waters 600E Pump Controller and 625 Pump

Waters 600E Pump Controller features 5-inch CRT Display, program tables with flow rate, gradient, timed events, 15 time-based step/table, 15 table capacity, and time-based multi-method capacity. Includes linking program table.

Waters 625 Pump has maximum system operating pressure of 4000 psi, accommodating all HPLC and FPLC methods, to achieve high resolution separations. A dynamic flow rate range of 0.01 to 5.00 ml/min allows versatile operation for microbore to preparative scale separations.

All in good condition and tested at GenTech. Includes SIX (6) MONTH WARRANTY.

Operational Specifications

Number of Solvents: One to four Modes of Operation: Gradient, isocratic, and flow programming Operating Flow Range: 0.00 to 10 ml/min (50 ul heads), in 0.01 ml increments. Composition Range: 0 to 100% programmable in 1 % increments for each of four reservoirs - A, B, C and D. Total composition must sum to 100%. Compositional Accuracy: Better than 1.0%, independent of pressure. Automatic Solvent Sparging: Standard, helium gas, input gas pressure range 50 to 150 psi. Helium flow rate range 0 to 100 ml/min, programmable to 1 ml/min. Pressure Maxima: 4000 psi over flow rate range Programmable Pressure Limits: - Upper 51 to 11000 psi - Lower 0 to 3950 psi Plunger Wash: 0.1 ml/min intermittent and automatic Program Storage: - Storage for sets of 15 tables (gradient, program event, and detector), with a maximum of 15 steps per table. - Storage for a time-based multi-method program with up to 48 individual steps. - EEPROM stores setup parameters and tables and preserves memory indefinitely following power loss or extended shutdown. Gradient Profiles: Eleven gradient curves CRT: Display: 5" (12.7 cm) diagonal screen. Sixteen lines with 40 characters per line. Displays current operating conditions. Allows operator to monitor complete gradient and timed event tables on single screens. Reverse video cursor prompts operator through program setup. Keyboard: Dedicated keys provide direct access to all display screens. Cursor movement keys simplify programming, editing and parameter entering. All keys are solvent resistant. Programmable Timed Events: Fifteen (15) timed events can be programmed a and stored for each table.
